Power and performance for your subwoofer system

Kenwood's Performance Series KAC-5001PS subwoofer amplifier can take care of your sub system's power requirements, and then some. With up to 500 watts RMS of power, you'll get clear, loud, and rockin' bass in your car. A rugged heat sink keeps this compact amp running at optimal temperatures, even when you're pushing your system hard.

Versatile adjustments and setup

A built-in low-pass filter lets you adjust the output so you'll get the best sound possible from your subwoofer/box combo. You can dial in up to 18 dB of bass boost if you want to fatten up the sound. An aluminum cover plate protects the amp's controls and connections, giving your installation a professional look.

Package deal: Save money when you buy this amp as part of these Kenwood dual 10" or dual 12" bass packages.

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Product Research

Features

CEA-2006 Compliant: CEA-2006 is a system of testing and
measurement methods for mobile audio amplifiers. This voluntary standard advocates
a uniform method for determining an amplifier's RMS power output and signal-to-noise
ratio. The criteria for measuring power uses a DC input voltage of 14.4 volts and
the RMS power output is measured into a 4-ohm load, with 1% or less Total Harmonic
Distortion (THD) plus noise, and over a frequency range of 20 Hz to 20 kHz, when
applicable (20-200 Hz for this subwoofer amp). Signal-to-Noise ratio is measured
in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms. CEA-2006
allows consumers to compare car amplifiers and receivers on an equal basis. Using
CEA-2006 criteria, the Kenwood KAC-5001PS is rated at 300 Watts RMS x 1 channel
with an 83 dBA signal to noise ratio.

Specifications: The manual also lists these non CEA-2006
compliant specifications:

Mono-Power Amp Design: The KAC-5001PS is designed with
specific features to power your subwoofer(s) with a frequency range between
20 and 200 Hz. This amplifier is not designed to power a full-range speaker.

Class D Amplifier Design: The amplifier design is Class D,
which uses digital switching power supplies. The result is much higher efficiency
(less heat generated) than Class AB.

Nice little amp

Decent enough amp. I always use the RCA inputs, so keep that in mind. Probably not actually as loud as they claim (300 to 500 watts), but with the input tuned in to at or about 11:30, this is a clean robust amplifier. Trying to drive a DVC RF 8" sub in a sealed enclosure & found out quick I'm going to need a bigger sub. So, if you plan on driving just one speaker with this amp, and you want the cleanest signal possible, definitely go with a 10 or 12 inch sub. And I'm a big fan of sealed cabs. I just find they sound that much deeper,. & cleaner (again with that word). What else can I say? Quite a bargain at $150. Wish they would have put a fan in her though. Oh well. What can you expect for less than $200? Nice bargain, worth the cash.

Pros:Clean, somewhat loud. Easy to wire up.

Cons:No fan. not quite as loud as Kenwood claims (probably closer to 150 to 200 watts at 4 ohms).

The only one star review on here... Sounds like he wires his R/L Preamps to his +/- speaker leads.

My opinion? This little thing packs quite the punch. Clean bass in a very small package. It looks nice, simple power on indicatior light that is easy to spot, the LPH works great, I enjoy everything about this amp so far. For the price, I wouldn't hesitate to reccomend this to my friends looking for a smaller one off sub set up

small but mighty

I have this amp hooked up to two infinity ref1260w in a sealed box and it pushes them great. Had it up halfway for 30 mins and it didn't even get warm can't wait to break subs in and fine tune it to see what this bad boy can do. Also for an amp that puts out this power its tiny compared to other amps in this wattage.

For its compact size, it does Great!

I have it powering a Kicker 10C124 12" 4ohm sub and it supplies all the power the sub asks for. It has just enough and the correct adjustment knob options to not cunfuse or intimidate a person that may be a first timer new to a speaker/sub install and adjustment. Its a small unit, so it doesn't take up alot of space, and, only having a small amount of room in my single cab truck, it was Exacly what I needed. I push the sub really hard and the Amp seems to barely run warm, and if I remember correctly, I have the gain at probably only 50-60% . Later this week I am going to wire in a Kenwood KFC-W12PS 12" 4ohm sub in parallel with the Kicker 12" its currently pushing. I do not doubt the amp at all for supplying the power that I will need to get the sound that I'm after.

Pros:Small/Compact Design. Right choice of adjustment knobs to get a good sounding sub adjustment.

Kenwood KAC-5001PS

I purchased this amp to compliment my Kenwood DVD player and my Kenwood 12" sub and I was really disappointed. I like Kenwood products and have never had an issue with anything I have ever purchased manufactured by Kenwood but this amp kept turning off when I turned up the volume. I checked the settings with customer support and all settings and connections were proper. Maybe I just received a bad one. I returned it for refund.
